Because of c) you seems to be right OTOH e.g. a natural tom or snare 
played two times does sound different to a drum sample played two times, 
while the first sample is cut, but if the first sample isn't cut it 
sounds relatively natural. Perhaps because of a time difference for the 
transient oscillation of the resonance head?
